针对污泥中有机质含量高且难降解,采用Fenton氧化法对污泥进行处理以达到降解污泥有机质的目的。研究了不同pH值条件下,加入不同配比的Fenton试剂对剩余污泥中有机质降解效果的影响,并通过孔隙结构试验与差热分析试验探讨有机质降解后的污泥微观结构变化。结果表明:Fenton试剂能将污泥中的有机质从30%降解至21%,处理后的污泥比表面积增大、孔容增大、孔径减小,污泥中的水分与有机质组成发生了改变。

In view of the high organic matter content in the sludge,and difficult to degrade,Fenton oxidation method was used to treat the sludge in order to degrade the organic matter. Under the condition of different pH value,the effects of organic matter degradation by adding different proportions of Fenton's reagent in the sludge were studied, and the changing microstructure of organic matter in the sludge was discussed through the pore structure test and differential thermal analysis test. The experiment results showed that: the organic matter in the sludge had been degraded from 30% to 21% by Fento...
